Glow Wire Test Apparatus mainly simulates the thermal stress test caused by heat sources or ignition sources such as burning elements or overload resistors in a short period of time. It is suitable for fire hazard tests of electrical and electronic products, household appliances, and their materials, and is also used for flameless ignition. Ignition source ignition test to determine the glow wire ignition temperature, flammability, and flame resistance index of related materials.
